BRUSH.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed April 16, 1914. Serial No. 832,175.

To all whom 2'2. may concern:

Be it known that I, RICHARD HALDEN- WANG, Jr., a citizen of the UnitedStates, and a resident of Brooklyn, in the county of Kings and State ofliaw York, have invented certain new and useful Improvements in Brushes,of which the following is a specification.

This invention relates to improvements in sanitary brush constructionand particularly to that class in which the brush holding elements areremovable from the frame.

The objects are to provide brushes, the bristle portions of which arecapable of sterilization without detriment to the frame or back portion,which may be removed or replaced without the use of any tools orappliances whatever and without disturbing the others, and which arerenewable when worn at a moderate expense. And finally, to provide abrush, parts of which may be dismounted so as to be carried flat in acase or pocket to avoid damage and save room in transportation. Theseobjects are attained by the novel combination of parts hereinafterdescribed and shown in the accompanying drawings, forming part of thisspecification, and in which:

Figure 1 is a perspective view of a brush Fig. 2 is a transverse sectionof the same. Fig. 3 is a longitudinal section of the same, the partsbeing disassociated. Fig. 4 is a perspective view showing a modificationof construction.

35 Fig. 5 is a fragmental view illustrating another method ofconstruction, and, Fig. 6 is a similar view showing the preferred formof construction, the parts being enlarged.

The invention comprises a frame which 0 may be of tubular or otherconstruction having a handle 10 connecting with parallel side members11, joined at their outer ends by a bar 12.

Extending between the side members, at

5 the end of the brush portion, is a rigidly connected bar 1.3, formingwith the side and front members a frame which may have attached anypreferred form of backing, metal or otherwise, and which may beornamented 0 as desired.

The brush holding elements are formed preferably of a tube or round rodhaving a plurality of openings 16 along one side, each openingcontaining a single brush tuft 5 or unit 17 of wires, bristles or otherfibrous material held in place in the common manner; all of whichelements are interchangeable, and one or more rows of which can be usedat one time. Both ends of these elements are turned downward so as tostand nearly parallel but slightly bent toward each other, and flattenedso that the front members 18 will engage within one of the verticalopenings 19 formed on the outer surface of the end bar 12. The othermember 20 is similarly fitted to suit the grooves 21 formed in theopposite outer surface. of the bar 13, the member being slightly bentinwardly forming a resilient hook that will remain in position when theknob is snapped into place over the bar.

In the modified form shown in Fig. 5, the front members of the brushholding elements 15 are reduced and formed into a pin like projection 25suited to engage in vertical openings 26 formed in the front bar 12, theopposite end being shaped as before described.

In the modification shown in Fig. 4, the brush holding element 15 isreduced at one end 30 suited to be received in horizontal openings 31formed in the front rail 12 while the opposite end is flattened andsplit forming two side members 31 and 32 normally sprung apart and whichmay be engaged in the slot 38 formed in the cross bar 13 so as to beheld under spring tension therein when assembled.

From the foregoing it will be seen that a moderate force exerted uponany of the bristle holding elements will serve to free them fromengagement with the main frame portion of the brush and it will beequally obvious that they can as readily be positioned without thenecessity of manipulating screws, clamps or other engaging means. Thusthese elements may be removed and subjected to sterilization by heat orchemical treatment and replaced without dificulty or the entire brushsubjected to similar treatment; it will also be evident that duplicatebrush holding elements may be inserted when desired and without theexpense of discarding the complete brush.

It will be apparent that other modifications may be made from thoseindicated and that the method of construction shown is applicable to awide range of brushes or similar articles.

Having thus described the invention, what I claim as new and seek tosecure by Letters Patent, is:

1. A brush comprising a rigid frame having an open back, a bar extendingfrom side to side therein at the rear of said frame, rods engaging withsaid frame and bar extending parallel with the sides, a plurality ofbrush tuft elements contained in said rods, and means combined with saidrods whereby said elements are held perpendicularly to said frame.

2. A brush comprising a rigid, substantially rectangular frame havingundercut spaced recesses in the end members thereof, brush tuft holdershaving ends resiliently engageable within the recesses in the endmembers of said frame, and means combined with said holders engageablewith the mentioned recesses.

3. A brush comprising a rigid, substan tially rectangular frame havingan open back and spaced openings formed in two of its oppositelydisposed members said openings being angularly disposed, a plurality ofsolid brush holding elements, and resilient projections formed at anangle upon said elements adapted to removably engage in the mentionedspaced openings.

4. A brush comprising an'open frame, its end members having a pluralityof angular recesses formed therein, solid, round, brush tuft holdersdisposed longitudinally of said 5. A' brush comprising a substantiallyrectangular open frame having front and rear members at the body portionthereof and a plurality of tuft holding elements, said elements allbeing held in tension between the said front and'rear members andremovable therefrom by pressure applied on the side-opposite the tufts.

6. A brush comprising an open frame, a barv extending between the sidemembers thereof, said bar and frame being recessed, tuft carryingelements each having a hook projection at one end andadownturned-projection terminating in a knob at the other end, all ofsaid projection members. being resiliently-engageable in the mentionedrecesses.

In witnesses whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
